There are millions being spent on this presidential election; money is coming from political parties, from each candidate's campaign and from outside groups. Some of the donations are from those looking out for themselves, some maybe hoping for paybacks and some just fighting for what they believe is right.

"We really don't know who those backers are, but they have millions of dollars to disburse and obviously they're doing it for a reason because they want a seat at the table. And with that kind of money, they're going to get it," Jerry Shuster, political analyst and University of Pittsburgh professor said.

Pittsburgh's Action News 4 has been sorting through the top contributors, tracking the money and breaking down the candidates cash.

According to the Center for Responsive Politics, the presidential candidates have raised $1.2 billion so far and another $576 million has been raised by superpacs supporting them.

The Center for Responsive Politics however does not track the Constitution Party candidate's money, but it tracks the others. They report that Clinton has received far more candidate committee money and Trump more outside money.

Clinton has received $445,412,163 in candidate committee money, more than double her nearest opponent Donald Trump, who has received $218,763,241. In outside money, though Trump has brought in $214,496,514, $43 million more than Clinton, who has received $171,240,103.

Johnson and Stein, the Libertarian and Green party candidates, are millions behind both. Stein has received $3,201.248 in candidate money and she has received no outside money. Johnson has received $10,649,405 in candidate committee money and $1,378,510 in outside money. Political analyst Jerry Shuster says these numbers matter.

"Ultimately that has a great deal of influence," Shuster said. "The average voter should have the same power at the seat of the table of Congress or the Senate or the presidency, but unfortunately money speaks."

According to the Center for Responsive Politics, Clinton's biggest contributor has donated more than $13 million. It is money that comes from employees of Paloma Partners, an investment company headquartered in Greenwich, Connecticut. Their founder is S. Donald Sussman. Sussman's estranged wife is Chellie Pingree, a Democratic member of the U.S. House of Representatives in Maine.

Trump's biggest contributor gave more than $15 million, and is listed as coming from employees of Renaissance Technologies, an investment management company out of New York. The CEO there is Robert Mercer, who "The Hill" has reported has had a say in who is running Trump's campaign.

For Johnson, employees of Morning Star Co. have contributed the most to his campaign, at $550,000. Morning Star is a Libertarian tomato processing company in California. They boast that no one there has a boss.

Stein's biggest contributor, donating just more than $5,000, comes from employees of Google, Inc. As most people know, Google is a widely used search engine, created in 1998 by men who met at Stanford. Although this employee donation went to the Green party, Google's founders typically support Democratic candidates.

These are some of the contributors easily tracked. Many are not.

"When you get in to some of these others groups, we're really not sure whether they're an environmental group or an anti-environmental group or whether they're just a splinter group with some really far out ideas because even the Supreme Court has ruled that they have a right to give anonymously and pretty much that's the way it goes," Shuster said. "It pretty much subliminates the ability of the average voter to have a great deal of power."

Some outside groups have given far more than the largest individual campaign contributions.
